What’s noteworthy is that Surface Book will be using Intel 6th Gen Skylake CPUs with SKUs under Core i5 and Core i7 series. Microsoft decided to rely on Microsoft’s GeForce GPU with GDDR5 memory. There’s no official word about the SKU that this unit is using, but it’s speculated that Microsoft Surface Book is using a Nvidia GTX 940M. There are a couple of variants that uses Intel’s on-chip graphic solution.

The notebook supports up to 16GB RAM. As far as display is concerned, it uses a 13.5″ 267 PPI panel with Microsoft PixelSense technology which is said to optimize latency and parallax. Microsoft assures that a full charge will last up to 12 hours.

The Surface Pro 4 tablet uses a 12.3″ PixelSense touchscreen display with a Surface Pen included. What’s interesting is that users can have a Surface Pro 4 based on your needs and requirements rather than relying on a tablet model with different storage variants. Apart from hardware customization choices, the following are the pre-set variants:

Intel Core m3 processor, 4GB RAM, 128GB storage – $900

Intel Core i5 processor, 4GB RAM, 128GB storage – $1,000

Intel Core i5 processor, 8GB RAM, 256GB storage – $1,300

Intel Core i5 processor, 16GB RAM, 256GB storage – $1,500

It should be noted that while choosing your tablet hardware via Microsoft Store, it offers a 1TB storage option once you select Intel Core i7 + 16GB RAM choice. What’s unfortunate is that despite the pre-orders are taken, the actual SKU of the CPU is not mentioned, and there’s no detail of the memory type (DDR3 or DDR4). Most likely it might be DDR4 to keep up with the times, but it’s safe to wait until Microsoft puts up more information.

Both devices use Windows 10 as one would expect.

While the pre-order can be done via Microsoft Store, you’ll need to wait until October 26th in the United States to pick it up from a brick-and-mortar store.

Edit (14.10.2015): Microsoft published newer photos of the Surface 4 Pro which shows every angle of the Windows 10 tablet.
